To all whom it may concern:

ject at 87 Waiblingerstrasse, Cannstatt, King- Be it known that 1, PAUL DAIMLER, subof the King of Wurttemberg, residing dom 'of Wurttemberg, Germany, have invented certain new and useful Improvements in Armored .Aerial Machines, of which the following is a specification.

This invention relates to propeller-drivenarmored aerial machines and constitutes an improvement in or-modificat on of the invention set forth in the specification of my copending application for a United States Patent Serial No. 785,084; filed August, 16, 1913, in which the propeller shaft of the aerial "machine is made hollow to receive a which may be discharged through the propeller shaft in the direction of flight, the

\propeller shaft being of sufliciently large internal diameter to enable the barrel ofthe gun to be adjusted therein for-sighting pur poses. This arrangement, however, permits of only a limited movement of the barrel of the gun within the hoilow propellershaft.

The object of the present invention is to enable the gun not only to be discharged throughthe hollow'propeller shaft, but also to be so directed as to discharge the projectile outside the periphery of the propeller blades thereby considerably increasing the range'of the gun.

According to the present invention the gun is arranged in alinement withthe axis of the hollow propeller shaft and behind the latter so that it is capable of being adjiisted at such an angleto the axis of the propeller shaft as to he directed outside the periphery of the propeller blades.

Preferably in order that the range of the gun is not limited by the intervention of .the motor, that is to say, in order to enable the gun to be directed-in any direction outside a the periphery ofthe propeller blades, the gun which is arran ed in alinement with the trated by way of example.

Figure l is a somewhat diagrammatic side view of the motor, propeller and gun, parts thereof being shown-in section. Fig. 2 is a similar view to Fig. 1 showing the arrangement of the gun intermediate the propeller shaft and motor. As shown. on Fig. 1 of the drawings the motor a drives the powerv shaft 3) which in turn transmits motion to the hollow propeller shaft 0 through the transmission gearing d, f. The hollow shaft 0 is of compar'atively 'short'length and carries at one end the propeller e. The gun g is arranged behind the hollow propeller shaft 0 so as to'benormally in alinement with the axis thereof, the gun 9 being mounted in any suitable manner in a swivel bearing a concentric withthe axis of the pro-v peller shaft 0.

As indicated by the shaded circle A in Fig. 1 of the drawings the gun g is capable of being adjusted at a slight angle to the axis of the ropeller shaft 0 so as to permit of the sightmg'of the gun through the propeller shaft, while the shaded triangular portion B- indicates the range of the gun outside the periphery of the blades of the propeller e.

It will :be clear from reference to Fig. 1- that the range of the gun outside the periphery of the propeller blades is limited to some extent by the motor a, but, as illus'- trated in Fig; 2, this may be overcome by extendingthe motor shaft 6 toward thepropeller 0 so that the gun 9 may be mounted in a position intermediate the motor a and the hollow propeller shaft 0, so that in this case the gun 9 may be directed in any direction outside the periphery of the propeller blades, as indicated by the shaded portion BinFig. 2.

H I claim .1. In a propeller-driven armored aerial I machine, the combination with'a hollow propeller shaft carrying the propeller, of a' gun arranged behind said shaft and in alinement with the, axis thereof, said gun being adapted to be adjusted at an angle to an. axis, thereby enabling the gun to shoot either through said shaft or at such an angle as to shoot outside the periphery of the propeller bladesn 2. In apropeller-driven armored aerial machine, the combination with a hollow propeller shaft carrying the propeller, of a gun arranged behind said shaft and in alinement with the axis thereof, and a swivel bearing for said gun for enabling the gun to be adjustedat an angle to said axis, whereby the gun may be directed either to shoot through said shaft or at such an angle as to shoot outside the periphery of the propeller blades.

, In a propeller-driven armored aerial machine, in combination, a motor having its power shaft extended toward the propeller, a hollow shaft driven from the extended end of said power shaft and carrying the propeller, and a gun located in alinement with the axis of said hollow shaft and intermediate said hollow shaft and motor, said gun being adapted to be adjusted at an angle to said axis to enable it to be directed to shoot either through said hollow shaft or outside the periphery of the propeller blades.

In a motor-driven armored aerial machine, In combination, a motor having its power shaft extended toward the propeller,

a hollow shaft driven from the extended end of said power shaft and carrying the propeller, a gun located in alinement with the axis of said hollow shaft and intermediate said hollow shaft and motor, and a swivel bearing for said gun for permitting adjustment of the gun at an angle to said axis to enable it to be directed to shoot either through said hollow shaft or outside the periphery of the propeller blades.

In testimony whereof I have aflixed my signature in presence of two witnesses.

PAUL-DAIMLER.
